Minimalist text only config

How-to
1

Description

Need help to understand the ABSOLUTE minimum flash/sram config to determine feasibility

What MCU/Processor/Board and compiler are you using?

Using ESP32 (IDF) with GCC 8.2.0. (2020r1)
Dev HW is ESP-WROVER-KIT v4 but will be running on custom hardware

What do you want to achieve?

Absolute minimalist configuration that supports text output ONLY, single font (8x8 or slightly bigger), ability to print text to a pre-selected position ie cursor control.

Objective is to use ~10KB Flash and ~4KB SRAM

What have you tried so far?

Nothing, this is a new project, have got the display initialized and working but must decide whether we can make LittlevGL work within the memory constraints, or have to develop own support.

Flash usage will be much more than 10k even with a very minimal configuration. Iā€™d say rather 64 kB.
If you need so basic features maybe a simpler library would fit better.
